Modern multimedia systems require flexibility, and the ability to display images from a smartphone to a large screen is becoming standard. Owners of Xiaomi and Redmi equipment often face the need to show photos to relatives, run a game on a full screen or present a work project without using a laptop. Fortunately, the Chinese manufacturer’s ecosystem offers several built-in and third-party solutions for this task.
The connection process can vary depending on your TV model (Mi TV, Android TV or global version with Google TV) and smartphone operating system. In this article, we will break down all the current methods, including wireless protocols and physical cable connection.
Whether you’re using a budget model or a flagship 4K display, the basic principles of Mi Remote and Android system features remain similar.We’ll take a closer look at network settings, as Wi-Fi connectivity is often a bottleneck when streaming high-resolution video.
Preparation of equipment and network
Before you start setting up, make sure that both your smartphone and your TV are connected to the same Wi-Fi network. This is a critical condition for most wireless protocols, such as Miracast or Google Cast. If your router supports dual-band, it is preferable to use a 5GHz network, as it provides higher bandwidth.
Check the software version on your TV. Go to Settings → About TV → System Update. Outdated firmware may not support new video coding standards or have vulnerabilities in the wireless module. On your smartphone, it is also worth checking for updates in the Systems Apps section.
⚠️ Note: If your router gives away two networks with the same name (2.4 GHz and 5 GHz), devices can automatically switch between them, which will cause a connection to break.
For a comfortable 4K broadcast, the LAN speed should be high. Make sure there are no thick concrete walls or powerful interference sources between the router and the TV. Ideally, for stationary devices such as the Mi Box or Smart TV, it is recommended to use a wired connection to the router via an Ethernet cable to free up the air for the smartphone.
☑️ Pre-broadcast checks
Use of the built-in Translation (Miracast) function
The most common way to do this is to use Miracast technology, which is that on Xiaomi PatchWall or Android TVs, this feature is often built into the system. You need to find an app called Wireless, Miracast or Translation in the list of installed programs on the TV.
When the app is launched, you'll have a wait for the connection on your TV screen. On a Xiaomi or Redmi smartphone, open the notification curtain and find the "Translation" button. If there's no button, click three dots in the corner of the curtain, select "Edit" and add this shortcut. The system will start looking for available displays.
When the name of your TV appears on the list, click on it. The TV screen may have a request for confirmation of connection, which must be coordinated by the remote control, then the image from the phone is fully mirrored to the large screen, which is ideal for demonstrating the interface of applications or games.
- 📱 Android: Translation in the curtain or the Connection and Sharing menu».
- 📺 Xiaomi TV: Application "Wireless broadcast" in the application menu.
- 🔌 Protocol: Works on the basis of the Wi-Fi Direct standard.
- ⏱️ Delay: Minimum, suitable for dynamic content.
Broadcasting via Google Home and Chromecast
If your TV is running Android TV or Google TV, it has built-in support for Chromecast technology, which is a more advanced protocol that allows you not just to duplicate the screen, but to send content directly from the server, unloading the smartphone.
Launch the Google Home app on your smartphone. It will automatically detect the TV on the network. Click on the device icon, then select the "Cast screen" button, and the system will alert you about possible traffic consumption and battery impact, and then the mirroring process will begin.
The thing about Chromecast is that many apps (YouTube, Netflix, Twitch) have their own live stream button inside the interface, and if you click on it, you can stream the video directly to the TV, and you can use the phone as a remote or for other tasks without interrupting the viewing.
Settings → Applications → Google Home → Permissions → Local Network (Enable)Make sure the Google Home app has permission to access the local network, otherwise it won’t be able to find the TV. Also check that the Chromecast built-in service is enabled on the TV in the app settings section.
What if Google Home doesn’t see TV?
Stream from iPhone to Xiaomi TV (AirPlay)
Apple device owners can also easily display an image on a Xiaomi TV, as many modern models support AirPlay 2 or have built-in AirPlay support. To check the settings of the TV and look for the "Apple AirPlay" section. If this option is not available, you may need to update the firmware or install the AirScreen app from the app store on the TV.
On iPhone, open Control Point (swipe down from the top right corner on new models or swipe up on old ones). Click Screen Replay (two rectangles). In the list, select your Xiaomi TV. If necessary, enter the code displayed on your TV screen in the field on your smartphone.
AirPlay transmissions are usually very high, with minimal image compression, and it's a great way to show photo albums or gallery videos at their best, but you should also consider that when you stream heavy games or 4K video, your smartphone can get hotter.
- 🍏 iOS: Control point → Screen replay.
- 📺 Xiaomi TV: Built-in AirPlay support or AirScreen app.
- 🔒 Security: Possibility of installation PIN-plug-in.
- 🎥 Quality: Support HDR Dolby Vision, if available.
⚠️ Note: When using AirPlay, make sure the TV is on the correct aspect ratio.Sometimes, content from the iPhone may be black boxed if the TV's scale settings are not automatically adapted.
Wired connection via HDMI and USB-C
For situations where the wireless network is overloaded or requires maximum image quality without compression, use a wired connection. You will need a USB-C to HDMI adapter. Importantly, not all Xiaomi smartphones support video output via the charging port. Support has flagship models with a USB 3.0/3.1 port (for example, the Mi 10/11/12/13 series Ultra, Mi Mix), while budget models often lack this feature.
Connect the adapter to your smartphone and the HDMI cable to your TV. Switch the TV signal source (Input button or Source on the remote) to the appropriate HDMI port 1/2/3. The image should appear automatically. You can choose between mirror or extended desktop (if MIUI/HyperOS is supported) in the phone settings.
This method also allows you to charge your smartphone while in use if the adapter has an additional power port, which is critical for long presentations or games, since the screen and video output consume a lot of power.
💡
Use HDCP adapters if you plan to stream secure content (Netflix, Disney+). Cheap Chinese adapters can only transfer desktop, blocking video in DRM-protected applications.
Comparison of connection methods
The best way to do this depends on your goals, and if you just want to show a photo, you can use wireless technology, you can use low ping for games, you can use the flow for movies, and you can see a table below that compares the main characteristics of the methods you've looked at.
| Method | Quality. | Delay. | Battery load |
|---|---|---|---|
| Miracast | High (Full HD/4K) | Low. | Tall. |
| Chromecast | Maximum (4K HDR) | Missing (streaming) | Medium |
| AirPlay | High. | Low. | Tall. |
| HDMI cable | No loss. | Zero. | Charging (+) |
Notice the column, "Battery load." Wi-Fi is in a constant, active data mode, which drains the battery quickly. Only wired HDMI allows you to simultaneously stream the image and charge the device, which makes the cable indispensable for marathons or long run.
💡
To watch online videos (YouTube, Netflix), always choose the built-in Translation button in the app, rather than mirroring the screen, which will save your phone’s charge and provide better picture quality.
Solution and optimization
If you're experiencing audio and video (lag) desynchronization, try lowering the output resolution in your broadcast settings or bringing your smartphone closer to the router. A common cause of problems is overheating your TV's Wi-Fi module when you're running for a long time. Let the device cool down or provide extra ventilation.
In some cases, cleaning the cache of the Wireless Broadcast app on your TV helps. Go to Settings → Apps → Wireless → Clear data. This will reset the connection settings and can eliminate program errors.
